Abstract Strictosidine β- d -glucosidase (E.C. 3.2.1.105) was partially purified fromsuspensionculturedcells of Tabernaemontanadivaricata . Three forms of different M r were found, which all specifically catalysed the deglucosylation of strictosidine ( K m 0.3–1 mM). Some enzyme characteristics resembled those described before for the Catharanthus roseus SG enzyme. Several products were shown to
摘要 胡豆苷β-d-葡萄糖苷酶(EC 3.2.1.105) 部分纯化自Tabernaemontana divaricata 悬浮培养细胞。发现了三种不同的 M r 形式,它们都特异性地催化了胡豆苷 (K m 0.3-1 mM) 的去葡萄糖基化。一些酶特性类似于之前描述的长春花 SG 酶的特性。表明在胡豆苷水解后形成了几种产物,其中鉴定了卡三胺、21-羟基阿马利辛和异戊烯二胺。
